Application inea June 4, ieee-.serial No; 113,649.

This invention relates to revoluble seats for vehicles, siieh as rail cars, and has for its object to atliord a co-operation ot' seat and pedestal which shall maintain v the kseat locked against rotation orieinoval eXcepjt the base ofthe pedestal, one arin oit which may be depressed yby the foot tocause the oti'ierarm to raise the. spindle slightly, Vthe lever also carrying an upwardly extending arm adapted in lockedv position toenter one oi' diametrically disposed locking ioriiied in a plate carried with thespindle.

The upwardly extending arm mayalso be formed -with. an enlarged portionl overlying` the plate to prevent accidental o r unauthor-- ized removal of the seat.

In order that the invention may be clearly understood `and readily carriedinto etlect4 the same will now be described more fully vwith reference to the accompanying draw-v ings illustrating a preferred einbodinient thereof, in which:

Figure l is a view showing, iii front elevation and partly in section, a pedestal and so much ot a seat as is necessary to show an understanding ot the invention.

Figure 2 a plan view showing the pedestal taken in the plane indicated by the line Q-fQ in Figure 1 and looking in the direction ot' the arrows.

Figure 3 locking means for the seat on the pedestal, Y taken in the vertical plane indicated by the line 3-3 in Figure l. l l

The seat L is mounted upon and rigidly secured to a downwardly depending spindle b journaled or rotatable ina cylindrical sleeve or bearing e secured against rotation :in the cylindrical base member d forming va part of the pedestal d. The seatv is reversed, or in fact turned to face in any direction, by turning it, and with it, of course, the spindle on which it is carried, with reference to the pedestal. It is normally locked against rotation and, particularly after 'a' weight has been supported thereby,l the 1ven'iova-l thereot. More particularly, a lever isv fulcrunied in is a fragmentary View showing spindle is rictionally held within the bearing sleeve. To ovei'coinegthis,friction and also to eii'ect the unlocking ofthe seat, `a ir'oot pedal e is depressed, :which being formed on a straight lever e ol tlie'tirst order, fulei'umed ,between its ends on the pivot d2 raises the arm e'j against the action of spring and causes the ball endetl to bearagainst the spherical bearing surface bj at the, bottom of the spindle b to raise the spindle within the bearing sleeveto break the rictional engagement and raise the flange d'iametrieally disposed tapered lugs L, H out ot the diaiiietrically disposed recesses c2,

Lever@ is also `formed with an arm e4 eX- tending upwardly through' a slot inthe pedestal and carrying a roller vetat its upperend which is adapted to enter one of diainetrically disposedrecessesg G and C3 termed in the peripheraledges of the re-. spective flanges g and c when the lever is not depressed to. `tirthei",lock thev flangesagainst relative displacement. When the lever is depressed, the arm e` is moved to the right, as viewed `Iin Figure l, carrying the roller e5 out of the recesses G', C3. yA slight i turn of the seat will now move the lugs la,

f H out of register with the recesses c2, G2 and the recess G out of register with the roller. The foot may then be taken oil' the pedal and the arm will then move to the left underl theY influence ofthe spring f and cause the roller to bear against the periphery'of the flange g. The seat may then continue to turn through 1800, the roller riding over the edge of the flange until the lugs are again in register 'with recesses, this't-iine, the 'respeca'i'vay from the llange c and thereby liftthe imV tive recesses which were before diainetrically,

oppositefto the lugs, cess g in the flange the roller.

and the opposite re- As the respective recesses lcome into position, the weight of the seat causes the `flange g to approach llange c, thetag in position to receive pered lugs i, H to drop into engagement in the lrecesses andthe roller to enter the lreeesses g C3. Extreme deflection of the pedal will move the' arm et outwardly far enough to cause the washer e6 carried above the rolleitoclear the flange g'and permit the complete reinoval of the spindle Z) out ofthe socket c; but inl ordinary circumstances, when the roller is riding on the periphery of the flange, the -Washer overlies that Vflange and `prevents accidental separation of the seat andpedestul. p r

Airevoliible seat has thus been provided .which is locked against unintentional dis- Placement erfxfemerels 'est is. easily depression ofa. foot pedal. i

Various modifications in the configuration ofthe component elements going to Ineke up the revoluble seat and4 its-docking devices as well es in the lookin `devices themselves n will* occur to those skiledin the art Without departing from the invention,`
